Jeff Bezos reported on his Bezos Expeditions website that one of his teams has located the engines from Apollo 11 at a depth of 14,000 feet, where they fell into the Atlantic on July 16, 1969.

The F-1 engines are some of the largest rocket engines ever built. Weighing 18,500 pounds, they're 19 feet tall. There's no doubt they're valuable should they be recovered intact; they're a priceless piece of the spacecraft that first took humankind to the Moon.

According to the NASA website, the Saturn S-1C first stage fell about 38 miles before hitting water roughly 55 miles downrange from Cape Kennedy. The majority of the stage is composed of aluminum and Inconel, and would not have corroded appreciably in saltwater. Likewise, the F-1 engines are composed of Inconel, aluminum, stainless steel and copper. All of those materials are relatively immune to seawater and might very well survive many years of immersion.

It's not clear just how much of the stage survived the impact itself. The tank would have fallen into the ocean at an angle, with the engines at the lower end. Bezos plans to find out, and will attempt to recover at least one, which he imagines NASA will donate to the Smithsonian.
